Definitions

  • the invention relates to a sewing dress for laminating support parts (moldings).
  • Laminating is understood to mean the joining of several layers of the same or different materials by means of suitable laminating agents, in particular by adhesive.
  • laminating a material can be protected or decorated.
  • in the automotive industry in the interior area increasingly frequently and large-scale components are laminated to decorate them in particular with leather or imitation leather, or with synthetic materials and to give them a higher quality appearance. This may concern, for example, the instrument carriers, the center consoles, the doors or the parcel shelves.
  • applications are conceivable, for example, in the aerospace or furniture industry. All in all, molded upholstery made of foam and elastomers but also hard molded components can be laminated.
  • a sewing dress is usually first made by connecting two or more sewing materials (reference elements) to one another via a functional seam.
  • the functional seams form a seam stub on the underside of the sewing garment. These seam stubs can be inserted into a groove designed for this purpose of the support part, also called seam trench.
  • the sewing dress must be aligned exactly on the carrier part. This is done by placing the sewing dress on the carrier part, the subsequent alignment of the functional seams of the sewing dress and the fixing of the aligned functional seam by means of seam swords.
  • the sewing dress must then be in the area of Functional seams are glued to the support member by manually activating the thermally activated adhesive present on the underside of the sewing dress by means of a H explicat Kunststoffföns in the vicinity of the functional seams. After this step, the functional seam can no longer slip.
  • the remaining sewing dress is prefixed by means of H composition compassionfön and activation of the thermally activated adhesive on the support member. Subsequently, the remaining sewing dress can be laminated process reliable with the carrier part, which usually takes place via distance or membrane laminating means of heat input. Due to the required manual prefixing of the sewing dress on the support part, the laminating of molded parts by means of seam swords is time-consuming and expensive. Manual prefixing requires a lot of operator training, so long training phases are required.
  • seam tape known that can be used to reinforce decorative stitching.
  • This seam tape has a rib or elevation in its longitudinal direction. After attaching the seam tape on the underside of the sewing dress, the exposed rib or elevation can engage in a seam trench of the support member and thus also serve the prefixing of the sewing dress on the support member. This can only take place in areas where a decorative seam is quilted.
  • a method for producing a sewing dress for laminating carrier parts in which the seam butt after sewing the functional seam is covered by a seam band to subsequently stabilize the functional seam.
  • the seam tape may be attached to the seam stub by means of an adhesive layer, in addition to which the seam tape may be sewn to the sewing dress by the decorative seams adjacent the seam.
  • the present invention seeks to provide an improved sewing dress for laminating carrier parts, which can be produced economically and can be prefixed as easily and quickly to the support member.
  • the sewing dress according to the invention for laminating support parts has at least one first and at least one second reference element, which are connected to one another via a functional seam, in particular a stitching seam.
  • the functional seam is present on the underside of the sewing garment to be applied to the carrier part and forms a seam stump from the edge regions of the two reference elements.
  • This seam stub is at least partially wrapped by a soft insert.
  • the fixing of the soft insert can in particular be effected by sewn into the functional seam.
  • the suture trench is regularly adjusted to the suture stub during the development phase.
  • the soft insert ensures that the suture stubs are widened in cross-section, so that the suture stubs can be fixed in the existing suture trenches and squeezed in, so that fixation is possible along all functional seams.
  • the suture stubs are thus securely fixed in an end position and sufficiently firmly connected to the support member so that they can hardly slip out of the suture trenches.
  • the insertion of the suture stub in the suture trenches of the support parts can still be done manually, with the squeezing of the soft insert into the suture trench requires only a slight manual pressure.
  • the sewing dress can be pre-positioned without further tools such as suture swords on the support part, which simplifies and accelerates the placement of the sewing clothes on the support parts.
  • the process risk is minimized because subsequent slippage of the seams from the suture trenches is prevented in subsequent process steps.
  • a fixing of the surfaces immediately adjacent to the functional seam can be omitted.
  • the pre-positioning of the sewing clothes is thus safe and reproducible, which lowers the scrap and increases the overall appearance of the laminated support members. Also, it is no longer necessary to pre-fix the suture stub first in the suture trenches of the molding by means of a hot air blower.
  • the soft insert may in particular be felt, leather, plastic, silicone, cardboard, cardboard, paper, rubber, granules, sponge rubber, fleece, wood or foam.
  • the soft insert may be formed, for example, as a textile insert of synthetic or natural materials. The hardness as well as the thickness and the strength of the soft insert may vary depending on the application.
  • the soft insert may be formed as a foam, as a nonwoven, as a compressed fiber material, as knitted fabric, as a fabric or as a film. It would also be possible to use an electrically conductive material as a soft insert. As a result, the soft insert could expand after fixing, for example by applying a voltage, so that slippage of the sewing dress from the carrier part can be reliably prevented.
  • the soft insert may be provided, at least in sections, with a solidification material in order to facilitate the mechanical processing of the soft insert, in particular by means of a sewing machine.
  • the hardening material has the task of influencing the expansion behavior of the soft insert so that the soft insert can no longer be stretched or compressed as desired, which would lead to an unclean sewing result.
  • the solidification material may be present on both sides of the soft insert, or even only on the top or the bottom of the soft insert. It may be present over the entire surface, or even only in the edge region of the soft insert, in which the detection of the soft insert takes place in particular by the sewing machine. It would also be possible to provide such a solidifying material only in the center of the soft insert.
  • the solidification material may in particular be a nonwoven, a knitted fabric, a foam, a flocking or a film. It would also be possible to use a liquid solidification material which solidifies upon application to the soft insert. Preferably, the solidification material should be sufficiently slippery to allow easy and low-friction transport in the sewing machine.
  • the seam stub can be wrapped in a particularly advantageous embodiment of a seam tape which is fixed by the functional seam.
  • the at least partially existing soft insert can in principle be present between the seam band and the seam stub or else on the outside of the seam band. If the soft insert is arranged on the outside of the seam band, a particularly good contact with the groove of the molded part can be produced. Also, the use of a seam tape without soft insert can bring significant benefits if the seam tape is sewn together with the functional seam and thus fixed by the functional seam.
  • the embodiment of a sewing dress with a seam stub, which is enveloped only by a seam band through the functional seam is fixed, is therefore of independent inventive importance.
  • the seam band may consist of or at least contain natural material or a synthetic material.
  • the seam tape may be a film, a nonwoven, a knit or a fabric.
  • a coating of the seam band would be possible.
  • an electrically conductive material as seam tape.
  • the thickness of the seam band can be in particular between 0.1 millimeter and 3 millimeters. It would also be possible to make the seam band correspondingly thicker.
  • the at least one soft insert may be present between the seam stub and the seam band.
  • the comparatively sensitive soft insert is thus protected by the seam band and can not be damaged during the processing steps for producing the Nähensteins, which would affect the subsequent function of the soft insert.
  • a particularly simple sliding in of the suture stub can be achieved in the seam trench by this arrangement.
  • Another advantage is that the suture stump covered by soft insert Although something is squeezed, but the outer seam band still allows a shift in the longitudinal direction of the suture trench to allow an exact alignment.
  • the soft insert can be arranged only in the region of the seam stub, but not in the region of the functional seam.
  • the optical seam pattern of the functional seam thus remains as unobtrusive as desired and it can not be accidentally visible point position in the region of the functional seam.
  • the functional seam is more stable thanks to the sewn-in seam band and thus runs optically more closed, more straightforward and quieter, so that a closed seam pattern is achieved.
  • the seam stub enveloped by the soft insert and optionally also by the seam tape can thereby have an approximately drop-shaped cross-section, in which the functional seam forms a taper.
  • Such a cross-section can be kept pressed particularly well in suture trenches.
  • the suture trenches could also have a corresponding taper, which would additionally improve the retention of the suture stumps in the suture trenches.
  • the seam tape may be perforated in the longitudinal direction at least in sections.
  • a centrally positioned perforation can facilitate the bending of the seam band when sewing into the functional seam, since the seam band can be folded more easily in the center.
  • the seam band lays evenly on both seam lugs, which means that the seam band can be grasped equally well by the functional seam on both sides.
  • the sewing dress can be easier to put on curves after completion of the functional seam through the perforation.
  • the inner soft insert may optionally also be in contact with the seam trench of the carrier part. This leads to an additional anti-slip effect, the slipping out of the suture stump from the suture trench and thus the slipping the Nähniks on the support member further difficult. This may be the case in particular in the case of an off-center perforation of the seam band.
  • the soft insert may also be formed perforated at least in sections in order to further facilitate bending when sewing into the functional seam, in particular in the region of curves.
  • the perforation of seam tape and / or soft insert can be realized for example by approximately angular cuts or a hole perforation.
  • a formation of the seam tape and / or the soft insert with openings of different shape and / or size or with slots would give such a perforation.
  • the seam tape can be sewn to the edge regions of the individual reference elements in order to bring about a faster fixation of the sewing clothes in the edge regions (turn-up regions).
  • the measures described above allow for a reduction in process times when prefixing the sewing clothes by a total of up to 60 percent in series production. It is also possible to dispense with the expensive prefixing systems with seaming blades, which can reduce the system costs of the prefixing systems by up to 80 percent. Instead of Vorfixieranlagen only a simple component receptacle is needed on which the carrier part to be laminated is attached. Also personnel and time costs for the pre-fixing can be reduced by up to 80 percent, since the pre-fixing of the sewing clothes on the support parts by means of seam swords and activation of the adhesive layers of the functional seams can be omitted and the process thus requires less training time.
  • At least one decorative seam may be present in the sewing dress, which is arranged at a certain distance from the functional seam and runs parallel to the functional seam.
  • two decorative seams can be present, which are arranged on both sides of the functional seam.
  • the decorative seams serve to visually revive the surface of the sewing garment, as they set accents and accentuate contours.
  • Decorative seams are increasingly regarded as a sign of special product quality and represent a decorative element of the backing elements laminated with leather or synthetic leather, especially in the interior of automobiles.
  • the seam tape can be provided with an adhesive on its outer side opposite the seam stub.
  • This adhesive may in particular be thermally activated and preferably have a low melting point, so that activation of the adhesive can take place even at relatively low temperatures.
  • the adhesive may be, for example, a PU film (polyurethane film) or a HotMelt film.
  • the seam trench could also be provided with an adhesive, for example also with a double-sided adhesive tape, in order to additionally fix the functional seam in the seam trench.
  • the production of such a sewing garment can for example take place in that first the functional seam is made, then in a separate step, the soft insert is attached to the seam stub of the functional seam and in a last step, the seam tape is sewn.
  • soft insert and seam tape can already be fastened to one another in advance, so that the fastening of seam tape and soft insert can take place in a single method step.
  • the seam tape with soft insert can already be sewn into this during sewing of the functional seam. This ensures a quieter and more harmonious appearance of the functional seam, since the seam tape additionally enhances the functional seam strengthens. Also, the functional seam gets more stability and is more tear resistant. In addition, no additional manufacturing steps for the production of the functional seam are required in this way.
  • a band may be used as shown in FIG DE 10 2012 100 891 A1 is described.
  • the soft insert can be arranged both centrally and off-center of the seam tape.
  • it has proven to be advantageous to perforate the seam band in the longitudinal direction.
  • the soft insert can basically already be pre-assembled on the seam band. However, it would also be possible to apply the soft insert only during the sewing process of the functional seam on the seam tape.
  • two soft inserts may be present on the seam band, which are arranged parallel to each other and with a certain mutual distance.
  • the perforation of the seam band may in this case preferably be formed in the region between the two soft inserts.
  • Such an embodiment with two spaced-apart soft inserts has the advantage that the teardrop-shaped cross section of the functional seam of the sewing dress is particularly simple and pronounced, since the seam stub is widened on both sides by the soft insert.
  • the seam trench of the support member does not have to be formed so deep because the soft insert does not completely surround the seam butt, but only on the sides of the seam stub is present. As a result, the seam stubs can be fixed particularly easily and securely in the seam trench of the carrier part. Such lateral crushing of the suture stub would thus be sufficient for attachment.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft ein Nähkleid zum Kaschieren von Trägerteilen (Formteilen). Unter Kaschieren versteht man das Verbinden mehrerer Lagen gleicher oder unterschiedlicher Materialien durch geeignete Kaschiermittel, insbesondere durch Klebstoff. Durch das Kaschieren kann ein Material geschützt oder dekoriert werden. Insbesondere in der Automobilindustrie werden im Innenraumbereich immer häufiger und großflächiger Bauteile kaschiert, um diese insbesondere mit Leder oder Lederimitaten, oder auch mit synthetischen Materialien zu dekorieren und diesen ein hochwertigeres Aussehen zu verleihen. Dies kann beispielsweise die Instrumententräger, die Mittelkonsolen, die Türen oder die Hutablagen betreffen. Anwendungen sind jedoch beispielsweise auch in der Luftfahrt- oder der Möbelindustrie denkbar. Insgesamt können Formpolster aus Schaum und Elastomeren aber auch harte Formbauteile kaschiert werden.The invention relates to a sewing dress for laminating support parts (moldings). Laminating is understood to mean the joining of several layers of the same or different materials by means of suitable laminating agents, in particular by adhesive. By laminating a material can be protected or decorated. In particular, in the automotive industry in the interior area increasingly frequently and large-scale components are laminated to decorate them in particular with leather or imitation leather, or with synthetic materials and to give them a higher quality appearance. This may concern, for example, the instrument carriers, the center consoles, the doors or the parcel shelves. However, applications are conceivable, for example, in the aerospace or furniture industry. All in all, molded upholstery made of foam and elastomers but also hard molded components can be laminated.

STAND DER TECHNIKSTATE OF THE ART

Zum Kaschieren von Trägerteilen wird regelmäßig zunächst ein Nähkleid angefertigt, indem zwei oder mehrere Nähgüter (Bezugselemente) über eine Funktionsnaht miteinander verbunden werden. Durch die Funktionsnähte wird auf der Unterseite des Nähkleids ein Nahtstummel gebildet. Diese Nahtstummel können in eine dafür konstruierte Nut des Trägerteils, auch Nahtgraben genannt, eingelegt werden. Das Nähkleid muss exakt auf dem Trägerteil ausgerichtet werden. Dies erfolgt durch das Auflegen des Nähkleids auf dem Trägerteil, das anschließende Ausrichten der Funktionsnähte des Nähkleids und des Fixierens der ausgerichteten Funktionsnaht mittels Nahtschwertern. Das Nähkleid muss anschließend im Bereich der Funktionsnähte auf dem Trägerteil verklebt werden, indem der auf der Unterseite des Nähkleids vorhandene thermisch aktivierbare Klebstoff mittels eines Heißluftföns in der Umgebung der Funktionsnähte manuell aktiviert wird. Nach diesem Schritt kann die Funktionsnaht nicht mehr verrutschen. Auch das restliche Nähkleid wird mittels Heißluftfön und Aktivierung des thermisch aktivierbaren Klebstoffs auf dem Trägerteil vorfixiert. Anschließend kann das restliche Nähkleid mit dem Trägerteil prozesssicher kaschiert werden, was in der Regel über Distanz- oder Membrankaschieren mittels Wärmeeinbringung erfolgt. Durch die erforderliche manuelle Vorfixierung des Nähkleids auf dem Trägerteil ist das Kaschieren von Formteilen mittels Nahtschwertern zeit- und kostenintensiv. Das manuelle Vorfixieren erfordert eine große Übung des Bedieners, so dass lange Einlernphasen erforderlich sind.To conceal carrier parts, a sewing dress is usually first made by connecting two or more sewing materials (reference elements) to one another via a functional seam. The functional seams form a seam stub on the underside of the sewing garment. These seam stubs can be inserted into a groove designed for this purpose of the support part, also called seam trench. The sewing dress must be aligned exactly on the carrier part. This is done by placing the sewing dress on the carrier part, the subsequent alignment of the functional seams of the sewing dress and the fixing of the aligned functional seam by means of seam swords. The sewing dress must then be in the area of Functional seams are glued to the support member by manually activating the thermally activated adhesive present on the underside of the sewing dress by means of a Heißluftföns in the vicinity of the functional seams. After this step, the functional seam can no longer slip. The remaining sewing dress is prefixed by means of Heißluftfön and activation of the thermally activated adhesive on the support member. Subsequently, the remaining sewing dress can be laminated process reliable with the carrier part, which usually takes place via distance or membrane laminating means of heat input. Due to the required manual prefixing of the sewing dress on the support part, the laminating of molded parts by means of seam swords is time-consuming and expensive. Manual prefixing requires a lot of operator training, so long training phases are required.

Aus der DE 10 2012 100 891 A1 ist ein Nahtband bekannt, das zur Verstärkung von Ziernähten eingesetzt werden kann. Dieses Nahtband weist in seiner Längsrichtung eine Rippe oder Erhebung auf. Nach dem Befestigen des Nahtbandes auf der Unterseite des Nähkleids kann die freiliegende Rippe oder Erhebung in einen Nahtgraben des Trägerteils eingreifen und somit ebenfalls der Vorfixierung des Nähkleids auf dem Trägerteil dienen. Dies kann nur in solchen Bereichen stattfinden, in denen eine Ziernaht aufgesteppt wird.From the DE 10 2012 100 891 A1 is a seam tape known that can be used to reinforce decorative stitching. This seam tape has a rib or elevation in its longitudinal direction. After attaching the seam tape on the underside of the sewing dress, the exposed rib or elevation can engage in a seam trench of the support member and thus also serve the prefixing of the sewing dress on the support member. This can only take place in areas where a decorative seam is quilted.

Aus der DE 10 2013 014 687 A1 ist ein Verfahren zum Herstellen eines Nähkleids zum Kaschieren von Trägerteilen bekannt, bei dem der Nahtstummel nach dem Nähen der Funktionsnaht von einem Nahtband umhüllt wird, um die Funktionsnaht nachträglich zu stabilisieren. Das Nahtband kann mittels einer Klebeschicht an dem Nahtstummel befestigt werden, zusätzlich dazu kann das Nahtband durch die neben der Funktionsnaht befindlichen Ziernähte an dem Nähkleid angenäht werden.From the DE 10 2013 014 687 A1 a method for producing a sewing dress for laminating carrier parts is known, in which the seam butt after sewing the functional seam is covered by a seam band to subsequently stabilize the functional seam. The seam tape may be attached to the seam stub by means of an adhesive layer, in addition to which the seam tape may be sewn to the sewing dress by the decorative seams adjacent the seam.

Aus der DE 10 2004 053 133 A1 ist ein Nähkleid zum Kaschieren von Trägerteilen bekannt, bei dem im Bereich der Funktionsnaht ein Positionierelement an der Unterseite des Nähkleids angebracht wird. Das Positionierelement wird an den aufgebogenen Nahtstummel der Funktionsnaht von unten angenäht, wobei die dazu erforderlichen Nähte auch auf der Vorderseite, der Sichtseite des Nähkleids, sichtbar sind. Der Nahtstummel muss dadurch verhältnismäßig lang ausgebildet sein, was einen erhöhten Materialbedarf mit sich bringt. Die Positionierelemente werden somit nicht durch die Funktionsnähte gehalten, sondern sind vielmehr mit den Ziernähten an das Nähkleid genäht worden.From the DE 10 2004 053 133 A1 is a sewing dress for laminating carrier parts is known, in which in the area of the functional seam Positioning element is attached to the underside of the sewing dress. The positioning is sewn to the bent seam stub of the functional seam from below, with the necessary seams on the front, the visible side of the sewing dress, are visible. The seam butt must therefore be made relatively long, which entails an increased material requirement. The positioning elements are thus not held by the functional seams, but rather have been sewn to the sewing dress with the decorative stitching.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem vorbekannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Nähkleid zum Kaschieren von Trägerteilen anzugeben, der wirtschaftlich günstig hergestellt werden kann und möglichst einfach und rasch an dem Trägerteil vorfixiert werden kann.Based on this prior art, the present invention seeks to provide an improved sewing dress for laminating carrier parts, which can be produced economically and can be prefixed as easily and quickly to the support member.

Das erfindungsgemäße Band zum Herstellen eines solchen Nähkleids ist durch die Merkmale des Anspruchs 11 gegeben. Sinnvolle Weiterbildungen der Erfindung sind Gegenstand von sich an diesen Anspruch anschließenden weiteren Ansprüchen.The band according to the invention for producing such a sewing garment is given by the features of claim 11. Useful developments of the invention are the subject of further claims that follow this claim.

Das erfindungsgemäße Nähkleid zum Kaschieren von Trägerteilen besitzt zumindest ein erstes und zumindest ein zweites Bezugselement, die über eine Funktionsnaht, insbesondere eine Steppnaht, miteinander verbunden sind. Die Funktionsnaht ist an der an dem Trägerteil anzulegenden Unterseite des Nähkleids vorhanden und bildet einen Nahtstummel aus den Randbereichen der beiden Bezugselemente. Dieser Nahtstummel wird zumindest abschnittsweise von einer Weicheinlage umhüllt. Das Fixieren der Weicheinlage kann insbesondere dadurch erfolgen, dass diese in die Funktionsnaht eingenäht wird.The sewing dress according to the invention for laminating support parts has at least one first and at least one second reference element, which are connected to one another via a functional seam, in particular a stitching seam. The functional seam is present on the underside of the sewing garment to be applied to the carrier part and forms a seam stump from the edge regions of the two reference elements. This seam stub is at least partially wrapped by a soft insert. The fixing of the soft insert can in particular be effected by sewn into the functional seam.

Bei neuen Trägerteilen wird der Nahtgraben regelmäßig während der Entwicklungsphase dem Nahtstummel angepasst. Die Weicheinlage sorgt dafür, dass die Nahtstummel im Querschnitt verbreitert werden, so dass sich die Nahtstummel in den vorhandenen Nahtgräben fixieren lassen und dort eingequetscht werden können, so dass entlang aller Funktionsnähte eine Fixierung möglich ist. Die Nahtstummel sind somit sicher in einer Endposition fixiert und ausreichend fest mit dem Trägerteil verbunden, so das diese kaum mehr aus den Nahtgräben rutschen können. Das Einlegen der Nahtstummel in die Nahtgräben der Trägerteile kann dabei nach wie vor manuell erfolgen, wobei das Einquetschen der Weicheinlage in die Nahtgräben lediglich einen leichten manuellen Druck erfordert. Das Nähkleid kann dadurch ohne weitere Werkzeuge wie beispielsweise Nahtschwerter auf dem Trägerteil vorpositioniert werden, was das Auflegen der Nähkleider auf den Trägerteilen vereinfacht und beschleunigt. Darüber hinaus wird das Prozessrisiko minimiert, da ein nachträgliches Herausrutschen der Nähte aus den Nahtgräben in nachfolgenden Verfahrensschritten verhindert wird. Somit kann ein Fixieren der Flächen unmittelbar neben der Funktionsnaht entfallen. Das Vorpositionieren der Nähkleider ist somit sicher und reproduzierbar, was den Materialausschuss senkt und die Optik der kaschierten Trägerteile insgesamt erhöht. Auch ist es nicht länger erforderlich, die Nahtstummel zunächst in den Nahtgräben des Formteils mittels eines Heißluftföns vorzufixieren.For new support parts, the suture trench is regularly adjusted to the suture stub during the development phase. The soft insert ensures that the suture stubs are widened in cross-section, so that the suture stubs can be fixed in the existing suture trenches and squeezed in, so that fixation is possible along all functional seams. The suture stubs are thus securely fixed in an end position and sufficiently firmly connected to the support member so that they can hardly slip out of the suture trenches. The insertion of the suture stub in the suture trenches of the support parts can still be done manually, with the squeezing of the soft insert into the suture trench requires only a slight manual pressure. The sewing dress can be pre-positioned without further tools such as suture swords on the support part, which simplifies and accelerates the placement of the sewing clothes on the support parts. In addition, the process risk is minimized because subsequent slippage of the seams from the suture trenches is prevented in subsequent process steps. Thus, a fixing of the surfaces immediately adjacent to the functional seam can be omitted. The pre-positioning of the sewing clothes is thus safe and reproducible, which lowers the scrap and increases the overall appearance of the laminated support members. Also, it is no longer necessary to pre-fix the suture stub first in the suture trenches of the molding by means of a hot air blower.

Bei der Weicheinlage kann es sich insbesondere um Filz, Leder, Kunststoff, Silikon, Karton, Pappe, Papier, Kautschuk, Granulate, Moosgummi, Vlies, Holz oder Schaumstoff handeln. Die Weicheinlage kann beispielsweise als textile Einlage aus synthetischen oder Naturmaterialien ausgebildet sein. Die Härte sowie die Dicke und die Festigkeit der Weicheinlage kann je nach Anwendungsfall unterschiedlich sein. Die Weicheinlage kann als Schaum, als Vlies, als verdichtetes Fasermaterial, als Gewirke, als Gewebe oder auch als Folie ausgebildet sein. Es wäre auch möglich, ein elektrisch leitfähiges Material als Weicheinlage zu verwenden. Dadurch könnte die Weicheinlage nach dem Fixieren beispielsweise durch das Anlegen einer Spannung expandieren, so dass ein Herausrutschen des Nähkleids aus dem Trägerteil zuverlässig verhindert werden kann.The soft insert may in particular be felt, leather, plastic, silicone, cardboard, cardboard, paper, rubber, granules, sponge rubber, fleece, wood or foam. The soft insert may be formed, for example, as a textile insert of synthetic or natural materials. The hardness as well as the thickness and the strength of the soft insert may vary depending on the application. The soft insert may be formed as a foam, as a nonwoven, as a compressed fiber material, as knitted fabric, as a fabric or as a film. It would also be possible to use an electrically conductive material as a soft insert. As a result, the soft insert could expand after fixing, for example by applying a voltage, so that slippage of the sewing dress from the carrier part can be reliably prevented.

Die Weicheinlage kann in einer besonders bevorzugten Ausführungsform zumindest abschnittsweise mit einem Verfestigungsmaterial versehen sein, um das maschinelle Verarbeiten der Weicheinlage insbesondere mittels einer Nähmaschine zu erleichtern. Das Verfestigungsmaterial hat dabei die Aufgabe, das Dehnungsverhalten der Weicheinlage so zu beeinflussen, dass sich die Weicheinlage nicht mehr beliebig dehnen oder stauchen lässt, was zu einem unsauberen Nähergebnis führen würde. Das Verfestigungsmaterial kann auf beiden Seiten der Weicheinlage vorhanden sein, oder auch nur auf der Ober- oder der Unterseite der Weicheinlage. Es kann vollflächig vorhanden sein, oder auch lediglich im Randbereich der Weicheinlage, in dem das Erfassen der Weicheinlage insbesondere durch die Nähmaschine erfolgt. Es wäre auch möglich, lediglich mittig der Weicheinlage ein solches Verfestigungsmaterial vorzusehen.In a particularly preferred embodiment, the soft insert may be provided, at least in sections, with a solidification material in order to facilitate the mechanical processing of the soft insert, in particular by means of a sewing machine. The hardening material has the task of influencing the expansion behavior of the soft insert so that the soft insert can no longer be stretched or compressed as desired, which would lead to an unclean sewing result. The solidification material may be present on both sides of the soft insert, or even only on the top or the bottom of the soft insert. It may be present over the entire surface, or even only in the edge region of the soft insert, in which the detection of the soft insert takes place in particular by the sewing machine. It would also be possible to provide such a solidifying material only in the center of the soft insert.

Bei dem Verfestigungsmaterial kann es sich insbesondere um ein Vlies, ein Gewirke, einen Schaum, eine Beflockung oder eine Folie halten. Es wäre auch möglich, ein flüssiges Verfestigungsmaterial zu verwenden, das sich nach dem Auftragen auf der Weicheinlage verfestigt. Vorzugsweise sollte das Verfestigungsmaterial ausreichend rutschfähig ausgebildet sein, um einen problemlosen und möglichst reibungsarmen Transport in der Nähmaschine zu ermöglichen.The solidification material may in particular be a nonwoven, a knitted fabric, a foam, a flocking or a film. It would also be possible to use a liquid solidification material which solidifies upon application to the soft insert. Preferably, the solidification material should be sufficiently slippery to allow easy and low-friction transport in the sewing machine.

Der Nahtstummel kann in einer besonders vorteilhaften Ausführungsform von einem Nahtband umhüllt werden, das durch die Funktionsnaht fixiert ist. Die zumindest abschnittsweise vorhandene Weicheinlage kann grundsätzlich zwischen Nahtband und Nahtstummel oder auch auf der Außenseite des Nahtbands vorhanden sein. Sofern die Weicheinlage auf der Außenseite des Nahtbands angeordnet ist, kann ein besonders guter Kontakt zur Nut des Formteils hergestellt werden. Auch die Verwendung eines Nahtbandes ohne Weicheinlage kann erhebliche Vorteile mit sich bringen, sofern das Nahtband gemeinsam mit der Funktionsnaht eingenäht wird und somit durch die Funktionsnaht fixiert wird. Die Ausführungsform eines Nähkleides mit einem Nahtstummel, der nur durch ein Nahtband umhüllt wird, das durch die Funktionsnaht fixiert wird, ist daher von eigenständiger erfinderischer Bedeutung. So kann auf diese Weise erstmals auch bei solchen Nähkleidern ein Nahtband verwendet werden, bei denen keine Ziernaht vorhanden sein soll. Bislang war eine Befestigung des Nahtbandes lediglich über eine Klebeschicht nicht als ausreichend angesehen worden, um eine reproduzierbare und sichere Befestigung des Nahtbandes an dem Nähkleid zu ermöglichen. Das Nahtband musste daher zwingend über die Ziernähte angenäht werden, so dass nur bei solchen Nähkleidern ein Nahtband möglich war, bei denen auch eine Ziernaht aufgebracht wurde. Dies ist jedoch nur bei einem verhältnismäßig geringen Anteil aller Nähkleider zum Kaschieren der Fall. Nunmehr können sämtliche Nähkleider, die zum Kaschieren von Trägerteilen eingesetzt werden sollen, mit einem Nahtband versehen werden, so dass eine Stabilisierung und Fixierung aller Funktionsnähte eines Nähkleides möglich wird.The seam stub can be wrapped in a particularly advantageous embodiment of a seam tape which is fixed by the functional seam. The at least partially existing soft insert can in principle be present between the seam band and the seam stub or else on the outside of the seam band. If the soft insert is arranged on the outside of the seam band, a particularly good contact with the groove of the molded part can be produced. Also, the use of a seam tape without soft insert can bring significant benefits if the seam tape is sewn together with the functional seam and thus fixed by the functional seam. The embodiment of a sewing dress with a seam stub, which is enveloped only by a seam band through the functional seam is fixed, is therefore of independent inventive importance. So can be used in this way for the first time in such Nähkleidern a seam tape in which no decorative seam should be present. Heretofore, attachment of the suture tape merely via an adhesive layer has not been considered sufficient to allow reproducible and secure attachment of the suture tape to the suture. The seam tape therefore had to be sewn on the decorative seams, so that only with such sewing dresses a seam band was possible, in which a decorative stitching was applied. However, this is only the case with a relatively small proportion of all sewing clothes for laminating the case. Now all sewing clothes that are to be used for laminating carrier parts, be provided with a seam band, so that a stabilization and fixation of all functional seams of a sewing dress is possible.

Das Nahtband kann aus Naturmaterial oder einem Synthetik-Material bestehen oder solches zumindest enthalten. Auch eine Kombination aus Natur- und Synthetik-Material wäre denkbar. Das Nahtband kann eine Folie, ein Vlies, ein Gewirke oder ein Gewebe sein. Gegebenenfalls wäre auch eine Beschichtung des Nahtbands möglich. Es wäre auch möglich, ein elektrisch leitfähiges Material als Nahtband zu verwenden. Die Dicke des Nahtbandes kann insbesondere zwischen 0,1 Millimeter und 3 Millimeter betragen. Es wäre auch möglich, das Nahtband entsprechend dicker auszubilden.The seam band may consist of or at least contain natural material or a synthetic material. A combination of natural and synthetic material would be conceivable. The seam tape may be a film, a nonwoven, a knit or a fabric. Optionally, a coating of the seam band would be possible. It would also be possible to use an electrically conductive material as seam tape. The thickness of the seam band can be in particular between 0.1 millimeter and 3 millimeters. It would also be possible to make the seam band correspondingly thicker.

In einer vorteilhaften Ausführungsform kann die zumindest eine Weicheinlage zwischen dem Nahtstummel und dem Nahtband vorhanden sein. Die vergleichsweise empfindliche Weicheinlage wird somit durch das Nahtband geschützt und kann nicht während der Verarbeitungsschritte zur Herstellung des Nähkleids beschädigt werden, was die spätere Funktion der Weicheinlage beeinträchtigen würde. Auch kann durch diese Anordnung ein besonders einfaches Hineingleiten des Nahtstummels in den Nahtgraben erreicht werden. Ein weiterer Vorteil ist der, dass der von Weicheinlage umhüllte Nahtstummel zwar etwas eingequetscht wird, das außen liegende Nahtband jedoch nach wie vor eine Verschiebung in Längsrichtung des Nahtgrabens ermöglicht, um eine exakte Ausrichtung zu ermöglichen.In an advantageous embodiment, the at least one soft insert may be present between the seam stub and the seam band. The comparatively sensitive soft insert is thus protected by the seam band and can not be damaged during the processing steps for producing the Nähkleids, which would affect the subsequent function of the soft insert. Also, a particularly simple sliding in of the suture stub can be achieved in the seam trench by this arrangement. Another advantage is that the suture stump covered by soft insert Although something is squeezed, but the outer seam band still allows a shift in the longitudinal direction of the suture trench to allow an exact alignment.

Vorzugsweise kann die Weicheinlage lediglich im Bereich des Nahtstummels, nicht aber im Bereich der Funktionsnaht angeordnet sein. Das optische Nahtbild der Funktionsnaht bleibt somit wie gewünscht maximal unauffällig und es kann nicht versehentlich Weichenlage im Bereich der Funktionsnaht sichtbar sein. Darüber hinaus erhält die Funktionsnaht durch das eingenähte Nahtband mehr Stabilität und verläuft dadurch optisch geschlossener, gradliniger und ruhiger, so dass ein geschlossenes Nahtbild erreicht wird.Preferably, the soft insert can be arranged only in the region of the seam stub, but not in the region of the functional seam. The optical seam pattern of the functional seam thus remains as unobtrusive as desired and it can not be accidentally visible point position in the region of the functional seam. In addition, the functional seam is more stable thanks to the sewn-in seam band and thus runs optically more closed, more straightforward and quieter, so that a closed seam pattern is achieved.

Der von Weicheinlage und gegebenenfalls auch von Nahtband umhüllte Nahtstummel kann dadurch einen etwa tropfenförmigen Querschnitt aufweisen, bei dem die Funktionsnaht eine Verjüngung bildet. Ein solcher Querschnitt kann besonders gut in Nahtgräben eingepresst gehalten werden. Auch könnten die Nahtgräben eine entsprechende Verjüngung aufweisen, was den Halt der Nahtstummel in den Nahtgräben zusätzlich verbessern würde.The seam stub enveloped by the soft insert and optionally also by the seam tape can thereby have an approximately drop-shaped cross-section, in which the functional seam forms a taper. Such a cross-section can be kept pressed particularly well in suture trenches. The suture trenches could also have a corresponding taper, which would additionally improve the retention of the suture stumps in the suture trenches.

In einer weiteren vorteilhaften Ausführungsform kann das Nahtband in Längsrichtung zumindest abschnittsweise perforiert ausgebildet sein. Eine mittig angeordnete Perforierung kann das Biegen des Nahtbandes beim Einnähen in die Funktionsnaht erleichtern, da sich das Nahtband mittig leichter falten lässt. Dadurch legt sich das Nahtband gleichmäßig auf beide Nahtfahnen, was dazu führt, dass das Nahtband beidseitig gleichermaßen gut von der Funktionsnaht erfasst werden kann. Auch lässt sich das Nähkleid nach dem Fertigstellen der Funktionsnaht durch die Perforation leichter in Kurven legen.In a further advantageous embodiment, the seam tape may be perforated in the longitudinal direction at least in sections. A centrally positioned perforation can facilitate the bending of the seam band when sewing into the functional seam, since the seam band can be folded more easily in the center. As a result, the seam band lays evenly on both seam lugs, which means that the seam band can be grasped equally well by the functional seam on both sides. Also, the sewing dress can be easier to put on curves after completion of the functional seam through the perforation.

Durch die Perforierung kann die innenliegende Weicheinlage gegebenenfalls auch Kontakt zu dem Nahtgraben des Trägerteils erhalten. Dies führt zu einem zusätzlichen Anti-Rutsch-Effekt, der das Herausrutschen des Nahtstummels aus dem Nahtgraben und damit das Verrutschen des Nähkleids auf dem Trägerteil weiter erschwert. Dies kann insbesondere bei einer außermittigen Perforation des Nahtbands der Fall sein.Through the perforation, the inner soft insert may optionally also be in contact with the seam trench of the carrier part. This leads to an additional anti-slip effect, the slipping out of the suture stump from the suture trench and thus the slipping the Nähkleids on the support member further difficult. This may be the case in particular in the case of an off-center perforation of the seam band.

Zusätzlich dazu kann auch die Weicheinlage zumindest abschnittsweise perforiert ausgebildet sein, um das Biegen beim Einnähen in die Funktionsnaht insbesondere im Bereich von Rundungen weiter zu erleichtern.In addition, the soft insert may also be formed perforated at least in sections in order to further facilitate bending when sewing into the functional seam, in particular in the region of curves.

Die Perforation von Nahtband und / oder Weicheinlage kann beispielsweise durch etwa winkelförmige Einschnitte oder eine Lochperforation realisiert werden. Auch eine Ausbildung des Nahtbandes und/oder der Weicheinlage mit Durchbrüchen verschiedener Form und/oder Größe oder mit Schlitzen würde eine solche Perforation ergeben.The perforation of seam tape and / or soft insert can be realized for example by approximately angular cuts or a hole perforation. A formation of the seam tape and / or the soft insert with openings of different shape and / or size or with slots would give such a perforation.

Das Nahtband kann an die Randbereiche der einzelnen Bezugselemente aufgenäht werden, um ein schnelleres fixieren der Nähkleider in den Randbereichen (Umbugbereichen) herbeizuführen.The seam tape can be sewn to the edge regions of the individual reference elements in order to bring about a faster fixation of the sewing clothes in the edge regions (turn-up regions).

Die oben beschriebenen Maßnahmen lassen eine Reduzierung der Prozesszeiten beim Vorfixieren der Nähkleider um insgesamt bis zu 60 Prozent in der Serienproduktion zu. Auch kann auf die teuren Vorfixieranlagen mit Nahtschwerter verzichtet werden, wodurch sich die Anlagenkosten der Vorfixieranlagen um bis zu 80 Prozent reduzieren können. Statt der Vorfixieranlagen wird lediglich noch eine einfache Bauteilaufnahme benötigt, auf der das zu kaschierende Trägerteil aufgesteckt wird. Auch Personal- und Zeitkosten für die Vorfixierung können um bis zu 80 Prozent reduziert werden, da das Vorfixieren der Nähkleider auf den Trägerteilen mittels Nahtschwertern und Aktivierung der Klebeschichten der Funktionsnähte entfallen kann und der Prozess somit weniger Anlernzeit erfordert.The measures described above allow for a reduction in process times when prefixing the sewing clothes by a total of up to 60 percent in series production. It is also possible to dispense with the expensive prefixing systems with seaming blades, which can reduce the system costs of the prefixing systems by up to 80 percent. Instead of Vorfixieranlagen only a simple component receptacle is needed on which the carrier part to be laminated is attached. Also personnel and time costs for the pre-fixing can be reduced by up to 80 percent, since the pre-fixing of the sewing clothes on the support parts by means of seam swords and activation of the adhesive layers of the functional seams can be omitted and the process thus requires less training time.

Vorzugsweise kann zumindest eine Ziernaht in dem Nähkleid vorhanden sein, die mit einem gewissen Abstand zur Funktionsnaht angeordnet ist und parallel zu der Funktionsnaht verläuft. Insbesondere können zwei Ziernähte vorhanden sein, die beidseitig der Funktionsnaht angeordnet sind. Die Ziernähte dienen dabei der optischen Belebung der Fläche des Nähkleids, da sie Akzente setzen und Konturen betonen. Ziernähte gelten zunehmend als Zeichen besonderer Produktqualität und stellen insbesondere im Innenbereich von Automobilen ein dekoratives Element der regelmäßig mit Leder oder Kunstleder kaschierten Trägerteile dar.Preferably, at least one decorative seam may be present in the sewing dress, which is arranged at a certain distance from the functional seam and runs parallel to the functional seam. In particular two decorative seams can be present, which are arranged on both sides of the functional seam. The decorative seams serve to visually revive the surface of the sewing garment, as they set accents and accentuate contours. Decorative seams are increasingly regarded as a sign of special product quality and represent a decorative element of the backing elements laminated with leather or synthetic leather, especially in the interior of automobiles.

In einer besonders bevorzugten Ausführungsform kann das Nahtband an seiner dem Nahtstummel gegenüber liegenden Außenseite mit einem Klebemittel versehen sein. Dieses Klebemittel kann insbesondere thermisch aktivierbar sein und vorzugsweise einen niedrigen Schmelzpunkt aufweisen, damit eine Aktivierung des Klebemittels bereits bei verhältnismäßig geringen Temperaturen erfolgen kann. Dadurch kann beim eigentlichen Kaschiervorgang ein zusätzliches Verkleben des Nahtstummels in dem Nahtgraben erfolgen, wodurch ein nachträgliches Verrutschen des Nähkleids auf dem Trägerteil weiter erschwert wird. Bei dem Klebemittel kann es sich beispielsweise um eine PU-Folie (Polyurethan-Folie) oder um eine HotMelt-Folie handeln. Zusätzlich oder alternativ dazu könnte auch der Nahtgraben mit einem Klebemittel, beispielsweise auch mit einem doppelseitigen Klebeband, versehen werden, um die Funktionsnaht zusätzlich in dem Nahtgraben zu fixieren.In a particularly preferred embodiment, the seam tape can be provided with an adhesive on its outer side opposite the seam stub. This adhesive may in particular be thermally activated and preferably have a low melting point, so that activation of the adhesive can take place even at relatively low temperatures. As a result, additional bonding of the seam stub in the seam trench can take place during the actual laminating process, which further complicates subsequent slippage of the sewing garment on the carrier part. The adhesive may be, for example, a PU film (polyurethane film) or a HotMelt film. Additionally or alternatively, the seam trench could also be provided with an adhesive, for example also with a double-sided adhesive tape, in order to additionally fix the functional seam in the seam trench.

Die Herstellung eines solchen Nähkleids kann beispielsweise dadurch erfolgen, dass zunächst die Funktionsnaht angefertigt wird, dann in einem separaten Arbeitsschritt die Weicheinlage an dem Nahtstummel der Funktionsnaht befestigt wird und in einem letzten Schritt das Nahtband angenäht wird. Vorzugsweise können Weicheinlage und Nahtband jedoch bereits im Vorfeld aneinander befestigt werden, so dass die Befestigung von Nahtband und Weicheinlage in einem einzigen Verfahrensschritt erfolgen kann. Dabei kann das Nahtband mit Weicheinlage bereits beim Nähen der Funktionsnaht in diese eingenäht werden. Dies sorgt für ein ruhigeres und harmonischeres Erscheinungsbild der Funktionsnaht, da das Nahtband die Funktionsnaht zusätzlich stärkt. Auch erhält die Funktionsnaht mehr Stabilität und ist reißfester. Darüber hinaus sind auf diese Weise keine zusätzlichen Fertigungsschritte für die Herstellung der Funktionsnaht erforderlich.The production of such a sewing garment can for example take place in that first the functional seam is made, then in a separate step, the soft insert is attached to the seam stub of the functional seam and in a last step, the seam tape is sewn. Preferably, however, soft insert and seam tape can already be fastened to one another in advance, so that the fastening of seam tape and soft insert can take place in a single method step. In this case, the seam tape with soft insert can already be sewn into this during sewing of the functional seam. This ensures a quieter and more harmonious appearance of the functional seam, since the seam tape additionally enhances the functional seam strengthens. Also, the functional seam gets more stability and is more tear resistant. In addition, no additional manufacturing steps for the production of the functional seam are required in this way.

Zum Herstellen eines oben beschriebenen Nähkleids kann beispielsweise ein Band verwendet werden, wie es in der DE 10 2012 100 891 A1 beschrieben ist. Die Weicheinlage kann dabei sowohl mittig als auch außermittig des Nahtbandes angeordnet sein. Im Gegensatz zu dem dort beschriebenen Band hat es sich jedoch als vorteilhaft herausgestellt, das Nahtband in Längsrichtung perforiert auszubilden.For producing a sewing garment described above, for example, a band may be used as shown in FIG DE 10 2012 100 891 A1 is described. The soft insert can be arranged both centrally and off-center of the seam tape. In contrast to the band described there, however, it has proven to be advantageous to perforate the seam band in the longitudinal direction.

Die Weicheinlage kann grundsätzlich bereits vorkonfektioniert an dem Nahtband vorhanden sein. Es wäre jedoch auch möglich, die Weicheinlage erst während des Nähprozesses der Funktionsnaht auf das Nahtband aufzubringen.The soft insert can basically already be pre-assembled on the seam band. However, it would also be possible to apply the soft insert only during the sewing process of the functional seam on the seam tape.

Darüber hinaus können vorzugsweise zwei Weicheinlagen an dem Nahtband vorhanden sein, die parallel zueinander und mit einem gewissen gegenseitigen Abstand angeordnet sind. Die Perforation des Nahtbandes kann in diesem Fall vorzugsweise im Bereich zwischen den beiden Weicheinlagen ausgebildet sein. Eine solche Ausführungsform mit zwei voneinander beabstandeten Weicheinlagen hat den Vorteil, dass sich der tropfenförmige Querschnitt der Funktionsnaht des Nähkleids besonders einfach und ausgeprägt ausbildet, da der Nahtstummel beidseitig durch die Weicheinlage verbreitert wird. Darüber hinaus muss der Nahtgraben des Trägerteils nicht so tief ausgebildet werden, da die Weicheinlage den Nahtstummel nicht vollständig umschließt, sondern lediglich an den Seiten des Nahtstummels vorhanden ist. Dadurch können die Nahtstummel besonders einfach und sicher in dem Nahtgraben des Trägerteils fixiert werden. Eine solche seitliche Quetschung des Nahtstummels wäre für die Befestigung somit ausreichend.In addition, preferably two soft inserts may be present on the seam band, which are arranged parallel to each other and with a certain mutual distance. The perforation of the seam band may in this case preferably be formed in the region between the two soft inserts. Such an embodiment with two spaced-apart soft inserts has the advantage that the teardrop-shaped cross section of the functional seam of the sewing dress is particularly simple and pronounced, since the seam stub is widened on both sides by the soft insert. In addition, the seam trench of the support member does not have to be formed so deep because the soft insert does not completely surround the seam butt, but only on the sides of the seam stub is present. As a result, the seam stubs can be fixed particularly easily and securely in the seam trench of the carrier part. Such lateral crushing of the suture stub would thus be sufficient for attachment.

In der Regel können die zwei Weicheinlagen auf derselben Seite des Nahtbands vorhanden sein. Es wäre jedoch auch möglich, zwei oder mehrere Weicheinlagen auf unterschiedlichen Seiten des Nahtbands vorzusehen. Ein Teil der Weicheinlagen könnte in diesem Fall nach dem Einnähen zwischen dem Nahtband und dem Nahtstummel des Nähkleids vorhanden sein, während ein anderer Teil der Weicheinlagen an der Außenseite des Nahtbandes angeordnet wäre. Dadurch wäre es auch möglich, die einzelnen Weicheinlagen mit unterschiedlichen Oberflächen zu versehen, so dass gezielt eine gut rutschende Weicheinlage oder eine Weicheinlage mit Anti-Rutsch-Wirkung verwendet werden könnte.As a rule, the two soft inserts can be present on the same side of the seam band. However, it would also be possible to have two or three provide several soft inserts on different sides of the seam band. A part of the soft inserts could in this case be present after sewing between the seam band and the seam stub of the sewing garment, while another part of the soft inserts would be arranged on the outside of the seam band. As a result, it would also be possible to provide the individual soft inserts with different surfaces, so that a well-sliding soft insert or a soft insert with anti-slip effect could be used in a targeted manner.

Weitere Vorteile und Merkmale der Erfindung sind den in den Ansprüchen ferner angegebenen Merkmalen sowie den nachstehenden Ausführungsbeispielen zu entnehmen.Further advantages and features of the invention can be found in the claims further specified features and the following embodiments.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

In den Fig. 1 und 2 ist eine erste Ausführungsform des erfindungsgemäßen Bandes 10 dargestellt. Das Band 10 besitzt ein Nahtband 12, das 0,1 bis 10,0 Millimeter dick ist. Vorzugsweise ist das Nahtband 12 zwischen 0,2 und 0,5 Millimeter dick, so dass sich das Nahtband 12 bei dem fertigen Nähkleid im an die Funktionsnaht anschließenden Bereich nicht abzeichnet. Mittig der Längsachse des Nahtbandes 12 ist eine Weicheinlage 14 angeordnet. Die Weicheinlage 14 kann zwischen 0,3 und 10,0 Millimeter dick sein. Im vorliegenden Beispielsfall ist die Weicheinlage 1,0 Millimeter dick.In the Fig. 1 and 2 a first embodiment of the tape 10 according to the invention is shown. The band 10 has a seam band 12 that is 0.1 to 10.0 millimeters thick. Preferably, the seam tape 12 is between 0.2 and 0.5 millimeters thick, so that the seam tape 12 in the finished sewing dress in subsequent to the functional seam Area not visible. In the middle of the longitudinal axis of the seam band 12, a soft insert 14 is arranged. The soft insert 14 may be between 0.3 and 10.0 millimeters thick. In the present example, the soft insert is 1.0 millimeters thick.

Die Weicheinlage 14 ist im vorliegenden Beispielsfall auf das Nahtband 12 aufgeklebt vorhanden. Alternativ dazu könnte die Weicheinlage 14 auch auf das Nahtband 12 aufgenäht sein. Auch andere Befestigungsmöglichkeiten von Weicheinlage 14 und Nahtband 12 wären grundsätzlich möglich.The soft insert 14 is glued on the seam tape 12 present in the present example case. Alternatively, the soft insert 14 could also be sewn onto the seam band 12. Other attachment options of soft insert 14 and seam tape 12 would be possible in principle.

Im vorliegenden Beispielsfall ist sowohl im Nahtband 12 als auch in der Weicheinlage 14 mittig entlang der Längsachse des Nahtbandes 12 eine Perforation in Form von mehreren Durchbrüchen 16 vorhanden, die in einem Abstand von etwa 4,5 Millimetern vorhanden sind. Die Durchbrüche 16 bilden eine Perforation, so dass das Band 10 besonders einfach entlang seiner Längsachse geknickt werden kann. Dies erleichtert das Einnähen des Bandes 10 in eine Funktionsnaht, da sich das Nahtband 12 besser in der dafür vorgesehenen Einfasshilfe der Nähmaschine faltet. Bei dem Band 10.3 gemäß Fig. 3 ist die Perforation in Weicheinlage 14.3 und Nahtband 12.3 in Form von mehreren Schlitzen 18 ausgebildet. Der Abstand und die Größe der Schlitze 18 und der Durchbrüche 16 kann an die jeweiligen Gegebenheiten angepasst werden, beispielsweise an das zu nähende Material des Nähkleids oder an die Breite beziehungsweise das Material von Weicheinlage und Nahtband. Die Form der Durchbrüche 16 kann individuell gewählt werden.In the present example, both in the seam band 12 and in the soft insert 14 centrally along the longitudinal axis of the seam band 12, a perforation in the form of a plurality of apertures 16 is present, which are present at a distance of about 4.5 millimeters. The openings 16 form a perforation, so that the band 10 can be bent particularly easily along its longitudinal axis. This facilitates the sewing of the tape 10 in a functional seam, since the seam tape 12 folds better in the designated Einfasshilfe the sewing machine. In the tape 10.3 according to Fig. 3 the perforation in soft insert 14.3 and seam tape 12.3 in the form of a plurality of slots 18 is formed. The distance and the size of the slots 18 and the apertures 16 can be adapted to the particular circumstances, for example, to the material to be sewn of Nähkleids or to the width or the material of the soft insert and seam tape. The shape of the openings 16 can be selected individually.

Im Gegensatz zu diesen hier dargestellten Ausführungsbeispielen könnte auch lediglich das Nahtband 12, 12.3 oder lediglich die Weicheinlage 14, 14.3 eine Perforation in Form von Durchbrüchen 16 oder Schlitzen 18 aufweisen.In contrast to these embodiments shown here, only the seam band 12, 12.3 or only the soft insert 14, 14.3 could have a perforation in the form of apertures 16 or slots 18.

Bei den hier dargestellten Ausführungsbeispielen reicht die Weicheinlage 14, 14.3 nicht bis an den äußeren Rand des Nahtbandes 12, 12.3. Dadurch ist die Weicheinlage 14, 14.3 regelmäßig nicht im Bereich der Funktionsnaht vorhanden. Im Gegensatz dazu könnte die Weicheinlage auch über die gesamte Breite des Nahtbandes reichen. In diesem Fall wäre die Weicheinlage auch im Bereich der Funktionsnaht vorhanden.In the embodiments shown here, the soft insert 14, 14.3 does not extend to the outer edge of the seam tape 12, 12.3. As a result, the soft insert 14, 14.3 is not regularly present in the region of the functional seam. In contrast, the soft insert could also extend over the entire width of the seam band. In this case, the soft insert would also be present in the area of the functional seam.

Eine alternative Ausführungsform des Bandes 10.4 gemäß den Fig. 4 und 5 sieht vor, insgesamt zwei Weicheinlagen 20, 22 an dem Nahtband 12 zu befestigen. Die beiden Weicheinlagen-Streifen 20, 22 verlaufen in diesem Fall parallel zueinander mit einem gewissen gegenseitigen Abstand. Entlang der Mittellinie des Nahtbandes 12 ist die Perforation in Form von Durchbrüchen 16 vorhanden, die von den Weicheinlagen-Streifen 20, 22 nicht verdeckt wird. Bei dem Band 10.6 gemäß Fig. 6 ist die Perforation in dem Nahtband 12.3 entsprechend Fig. 3 in Form von mehreren Schlitzen 18 ausgebildet.An alternative embodiment of the tape 10.4 according to the 4 and 5 provides for a total of two soft inserts 20, 22 to be attached to the seam band 12. The two soft insert strips 20, 22 extend in this case parallel to each other with a certain mutual distance. Along the center line of the seam tape 12, the perforation in the form of apertures 16 is present, which is not obscured by the soft insert strips 20, 22. In the band 10.6 according to Fig. 6 is the perforation in the seam band 12.3 accordingly Fig. 3 formed in the form of a plurality of slots 18.

Bei dem Band 10.4, 10.6 könnte im Gegensatz zu dem hier dargestellten Ausführungsbeispiel auf die mittige Perforation in Form von Durchbrüchen 16 und/ oder Schlitzen 18 auch verzichtet werden, da das Nahtband 12, 12.3 in diesem Fall durch die im mittleren Bereich fehlende Weicheinlage bereits recht gut mittig geknickt werden kann.In the band 10.4, 10.6 could be dispensed with in contrast to the embodiment shown here on the central perforation in the form of openings 16 and / or slots 18, since the seam tape 12, 12.3 in this case by the lack of soft insert in the middle area already quite can be kinked in the middle.

Es wäre auch möglich, das Nahtband 12, 12.3 zusätzlich oder alternativ zu der mittigen Perforation mit einer seitlichen Perforation zu versehen, die im Bereich der Weicheinlage 14, 14.3 beziehungsweise 20, 22 vorhanden wäre. Eine solche seitliche Perforation könnte beispielsweise durch Durchbrüche, Schlitze oder sonstige Einschnitte realisiert werden. Durch diese seitliche Perforation kann die Weicheinlage 14, 14.3, 20, 22 in direkten Kontakt mit dem Nahtgraben des Trägerteils gelangen, was zu einer besseren Haftung des Nähkleids an der Nahtgrabenwand führt und die Vorfixierung des Nähkleids an dem Trägerteil weiter erleichtert.It would also be possible to provide the suture band 12, 12.3 additionally or alternatively to the central perforation with a lateral perforation which would be present in the region of the soft insert 14, 14.3 or 20, 22. Such a lateral perforation could be realized for example through openings, slits or other cuts. As a result of this lateral perforation, the soft insert 14, 14.3, 20, 22 can come into direct contact with the seam trench of the carrier part, which leads to a better adhesion of the sewing garment to the seam trench wall and further facilitates the prefixing of the sewing garment to the carrier part.

Im Gegensatz zu den in den Fig. 4 bis 6 dargestellten Ausführungsformen könnte auch auf einen der beiden Weicheinlagen-Streifen 20, 22 verzichtet werden. In diesem Fall wäre die Weicheinlage nicht mehr genau mittig des Nahtbandes 12 vorhanden.Unlike in the 4 to 6 illustrated embodiments could also on one of the two soft insert strips 20, 22nd be waived. In this case, the soft insert would no longer be exactly in the center of the seam band 12.

Fig. 7 und 8 zeigen eine erste Ausführungsform des erfindungsgemäßen Nähkleids 30 vor und nach dem Einlegen der Funktionsnaht 32 in einen Nahtgraben 34 eines Trägerteils 36. Das Nähkleid 30 besitzt zwei Bezugselemente 40, 42, die mittels einer Funktionsnaht 32 aneinander befestigt sind. Die beiden Bezugselemente 40, 42 sind im vorliegenden Beispielsfall aus Leder oder Kunstleder, grundsätzlich sind jedoch auch andere Materialien der Bezugselemente 40, 42 denkbar. Durch die Funktionsnaht 32 bildet sich an der Unterseite 44 ein Nahtstummel 46, auch Nahtfahne genannt. Die Breite 48 des Nahtstummels 46 ist regelmäßig etwas geringer als die Breite 50 des Nahtgrabens 34 des Trägerteils 36. FIGS. 7 and 8 show a first embodiment of the sewing garment 30 according to the invention before and after inserting the functional seam 32 in a seam trench 34 of a support member 36. The sewing dress 30 has two reference elements 40, 42 which are fastened together by means of a functional seam 32. The two reference elements 40, 42 are in the present example of leather or synthetic leather, but in principle, other materials of the reference elements 40, 42 are conceivable. Through the functional seam 32 forms at the bottom 44 a seam stub 46, also called seam flag. The width 48 of the seam stub 46 is regularly slightly smaller than the width 50 of the seam trench 34 of the support member 36th

Der Nahtstummel 46 wird im vorliegenden Beispielsfall von einem Band 10 entsprechend Fig. 1 und 2 umhüllt. Das Nahtband 12 ist dabei direkt in die Funktionsnaht 32 eingenäht vorhanden. Die Breite der Weicheinlage 14 ist so gewählt, dass im Bereich der Funktionsnaht 32 keine Weicheinlage 14 vorhanden ist. Dies sorgt für eine harmonische und optisch ruhige Funktionsnaht. Durch die vorhandene Weicheinlage 14 entsteht ein etwa tropfenförmiger Querschnitt des von Weicheinlage 14 und Nahtband 12 umhüllten Nahtstummels 46, dessen maximale Breite 52 etwas größer ist als die Breite 50 der Nut 34 des Formteils 36.The seam stub 46 is corresponding in the present example of a band 10 Fig. 1 and 2 envelops. The seam tape 12 is sewn directly into the functional seam 32. The width of the soft insert 14 is selected so that no soft insert 14 is present in the region of the functional seam 32. This ensures a harmonious and visually quiet functional seam. Due to the existing soft insert 14 creates an approximately drop-shaped cross-section of the soft insert 14 and seam tape 12 wrapped seam stub 46 whose maximum width 52 is slightly greater than the width 50 of the groove 34 of the molding 36th

Die Verankerung des Nähkleids 10 in dem Nahtgraben 34 des Trägerteils 36 (siehe Fig. 8) erfolgt durch eine Verdrängung der Weicheinlage 14 während des Hineinschiebens des Nahtstummels 46 in die dafür vorgesehene Nut 34. Dadurch kommt es zu einer Quetschung der Weicheinlage 14 und somit zu einer Arretierung des Nahtstummels 46 und damit auch des Überzugs 10 in dem dafür konstruierten Nahtgraben 34. Es kommt somit zu einer Positionierung der Funktionsnähte 32, die nun so vorfixiert sind, dass das restliche Nähkleid 10 ebenfalls vorfixiert werden kann.The anchoring of the sewing garment 10 in the seam trench 34 of the support member 36 (see Fig. 8 ) is effected by a displacement of the soft insert 14 during the insertion of the suture stub 46 into the groove 34 provided for. This results in a squeezing of the soft insert 14 and thus arresting of the suture stub 46 and thus also of the cover 10 in the suture trench 34 constructed therefor Thus, there is a positioning of the functional seams 32, which are now prefixed so that the remaining sewing dress 10 can also be prefixed.

Im Gegensatz zu dem hier dargestellten Ausführungsbeispiel könnte das Nähkleid 10 auch mittels eines herkömmlichen Nahtbandes und einer streifenförmigen Weicheinlage hergestellt werden, ohne dass Nahtband und Weicheinlage zunächst aneinander befestigt werden müssten. Nahtband und Weicheinlage könnten also erst während des Nähprozesses zum Fertigen der Funktionsnaht miteinander verbunden werden. In diesem Fall könnte eine erste Bandspule das Nahtband vorrätig halten und eine zweite Bandspule die Weicheinlage. Beide Bandspulen könnten übereinander, nebeneinander, hintereinander oder auch an unterschiedlichen Plätzen der Nähmaschine oder des Arbeitsplatzes angebracht werden, so dass Nahtband und Weicheinlage parallel zueinander und unmittelbar übereinander angeordnet in die Nähmaschine einlaufen würde. Die Weicheinlage und das Nahtband können im Werkzeug der Nähmaschine kontrolliert geführt werden, um den Randbereich der beiden Bezugselemente gelegt werden, und durch die Funktionsnaht an dem Nähkleid befestigt werden. Dabei kann es ausreichend sein, lediglich das Nahtband durch die Funktionsnaht zu befestigen, während die Weicheinlage quasi lose zwischen dem Nahtstummel und dem Nahtband zu liegen käme. Da das Nahtband jedoch ausreichend stramm an dem Nahtstummel anliegt, kann ein Verrutschen der Weicheinlage ausgeschlossen werden.In contrast to the exemplary embodiment illustrated here, the sewing dress 10 could also be produced by means of a conventional seam tape and a strip-shaped soft insert, without the seam tape and soft insert first having to be fastened to one another. Suture band and soft insert could thus be connected to each other during the sewing process to fabricate the functional seam. In this case, a first reel could hold the seam band in stock and a second reel could hold the soft insert. Both reels could be mounted one above the other, side by side, one behind the other, or at different locations of the sewing machine or the work station, so that the seam tape and the soft insert would run parallel to each other and arranged directly above one another in the sewing machine. The soft insert and the seam band can be controlled in the tool of the sewing machine to be placed around the edge region of the two reference elements, and be attached by the functional seam on the sewing dress. It may be sufficient to fasten only the seam tape through the functional seam, while the soft insert would come to rest almost loosely between the seam stub and the seam tape. However, since the seam tape is sufficiently tight against the seam stub, slippage of the soft insert can be ruled out.

Eine zweite Ausführungsform des erfindungsgemäßen Nähkleids 30.2 ist in Fig. 9 dargestellt. Bei dem Nähkleid 30.2 wurde statt des Bandes 10 gemäß Fig. 1 das Band 10.4 gemäß Fig. 4 zum Umhüllen des Nahtstummels 46 verwendet. Auch dadurch kann ein etwa tropfenförmiger Querschnitt des von den beiden Weicheinlage-Streifen 20, 22 und dem Nahtband 12 umhüllten Nahtstummels 46 realisiert werden.A second embodiment of the sewing garment 30.2 according to the invention is shown in FIG Fig. 9 shown. In the sewing dress 30.2 was instead of the tape 10 according to Fig. 1 the band 10.4 according to Fig. 4 used to wrap the seam stub 46. This also allows an approximately drop-shaped cross section of the two soft insert strips 20, 22 and the seam tape 12 wrapped seam stub 46 can be realized.

Entsprechend Fig. 10 kann bei einer alternativen Ausführungsform des Überzugs 30.3 auch lediglich eine Weicheinlage 14 verwendet werden. In diesem Fall wird die Weicheinlage 14 mittels der Funktionsnaht 32 an dem Nahtstummel 46 angenäht. Die Außenseite der Weicheinlage 14 kann mit einer Rutschbeschichtung versehen sein, um das Einnähen der Weicheinlage 14 in die Funktionsnaht 32 zu erleichtern. Die Weicheinlage könnte in diesem Fall auch durch ein weiches, dickes Nahtband mit einer Dicke von etwa 0,3 bis 5,0 Millimetern realisiert werden.Corresponding Fig. 10 In an alternative embodiment of the coating 30.3, only one soft insert 14 can be used. In this case, the soft insert 14 is sewn to the seam stub 46 by means of the functional seam 32. The outside of the soft insert 14 may be provided with a slip coating to facilitate sewing the soft insert 14 into the functional seam 32. The soft insert could also be realized in this case by a soft, thick seam tape with a thickness of about 0.3 to 5.0 millimeters.

Es wäre auch möglich, an den beiden Außenseiten des Nahtstummels 46 jeweils einen Weicheinlagen-Streifen 20, 22 zu befestigen. Ein solches Nähkleid 10.4 ist in Fig. 11 dargestellt. Auch in diesem Fall können die beiden nach außen weisenden Seiten der Weicheinlagen-Streifen 20, 22 jeweils mit einer Rutschbeschichtung versehen werden. Die beiden Weicheinlagen-Streifen 20, 22 können beispielsweise auf die Unterseite der beiden Bezugselemente 40, 42 geklebt werden und beim Nähen der Funktionsnaht 32 von dieser mit erfasst werden. Es wäre auch möglich, die beiden Weicheinlagen-Streifen 20, 22 nicht durch die Funktionsnaht 32 zu erfassen; die Weicheinlagen-Streifen 20, 22 müssten dann auf andere geeignete Weise an dem Nahtstummel 46 fixiert werden. Dies kann beispielsweise durch einen Klebevorgang oder einen Heftvorgang erfolgen.It would also be possible to attach to the two outer sides of the seam stub 46 each have a soft insert strips 20, 22. Such a sewing dress 10.4 is in Fig. 11 shown. Also in this case, the two outwardly facing sides of the soft insert strips 20, 22 can each be provided with a slip coating. The two soft insert strips 20, 22 can, for example, be glued to the underside of the two reference elements 40, 42 and be grasped by the latter when sewing the functional seam 32. It would also be possible not to detect the two soft insert strips 20, 22 by the functional seam 32; the soft insert strips 20, 22 would then have to be fixed to the suture stub 46 in some other suitable manner. This can be done for example by a gluing process or a stapling process.

Sofern die Weicheinlagen-Streifen 20, 22 beziehungsweise die Weicheinlage 14 gemäß Fig. 10 nicht von der Funktionsnaht 32 erfasst wird, kann sich oberhalb der Funktionsnaht 32 auch kein Überwurf 54 bilden, der sich nach dem Kaschieren des Nähkleids 30.3, 30.4 an dem Trägerteil 36 auf der kaschierten, sichtbaren Oberfläche desselben abzeichnen könnte.If the soft insert strips 20, 22 or the soft insert 14 according to Fig. 10 is not detected by the functional seam 32, above the functional seam 32 also can not form a wrap 54, which could be the same after the lamination of the Nähkleids 30.3, 30.4 on the support member 36 on the laminated, visible surface thereof.

Das Nähkleid 30.4 gemäß Fig. 11 kann in einem zweiten Verarbeitungsschritt nachträglich mit einem Nahtband 12 versehen werden, so dass das in Fig. 12 dargestellte Nähkleid 30.5 entsteht. Dazu wird das Nahtband 12 über eine weitere Funktionsnaht 56 nachträglich angenäht. Die beiden Funktionsnähte 32, 56 können dabei etwa auf gleicher Höhe angeordnet werden, so dass sich von der Vorderseite des Nähkleids 10.5 ein optisch ansprechendes Bild ergibt.The sewing dress 30.4 according to Fig. 11 can be subsequently provided with a seam tape 12 in a second processing step, so that the in Fig. 12 illustrated Nähkleid 30.5 arises. For this purpose, the seam tape 12 is subsequently sewn over a further functional seam 56. The two functional seams 32, 56 can be arranged approximately at the same height, so that there is a visually appealing image from the front side of the sewing garment 10.5.

In vergleichbarer Weise könnte auch das Nähkleid 10.3 gemäß Fig. 10 nachträglich mit einem Nahtband 12 versehen werden. Es wäre auch möglich, in Abwandlung von Fig. 11, lediglich auf einer Seite des Nahtstummels einen Weicheinlage-Streifen 20 oder 22 aufzubringen. Auch in diesem Fall wäre es möglich, den Nahtstummel nachträglich von einem Nahtband zu umschließen, um den einseitigen Weicheinlage-Streifen an dem Nahtstummel zu fixieren.In a similar way, the sewing dress 10.3 according to Fig. 10 be subsequently provided with a seam tape 12. It would also be possible, in modification of Fig. 11 , only on one side of the seam stub to apply a soft insert strip 20 or 22. Also in this case, it would be possible to subsequently enclose the seam stub of a seam tape in order to fix the one-sided soft insert strip on the seam stub.

Alternativ wäre auch denkbar, den genähten Nahtstummel durch ein Silikontauchbad, ein Kunststofftauchbad oder ein Kautschuktauchbad zu führen, um eine geeignete Tropfenform zu erreichen. Es wäre auch möglich, eine Kunststoffummantelung aufzusprühen.Alternatively, it would also be conceivable to guide the sewn seam stub through a silicone immersion bath, a plastic immersion bath or a rubber immersion bath in order to achieve a suitable drop shape. It would also be possible to spray on a plastic sheath.

Eine sechste Ausführungsform des erfindungsgemäßen Nähkleids 30.6 ist in Fig. 13 dargestellt. Bei dem Nähkleid 30.6 wurde lediglich ein Nahtband 60 ohne zusätzliche Weicheinlage zum Umhüllen des Nahtstummels 46 verwendet. Das in die Funktionsnaht 32 eingenähte Nahtband 60 kann die Funktionsnaht 32 fixieren und stabilisieren und trägt somit zu einem optisch ansprechenden Bild des Nähkleids 30.6 bei.A sixth embodiment of the sewing garment 30.6 according to the invention is shown in FIG Fig. 13 shown. In the case of the sewing dress 30.6, only one seam band 60 without additional soft insert was used to cover the seam stub 46. The seam band 60 sewn into the functional seam 32 can fix and stabilize the functional seam 32 and thus contributes to a visually appealing image of the sewing garment 30.6.

In den Fig. 14 und 15 ist eine Weicheinlage 70 dargestellt, bei der auf die Verwendung eines zusätzlichen Nahtbandes verzichtet werden kann. Die Weicheinlage 70 ist im vorliegenden Beispielsfall sowohl auf ihrer Oberseite 72 als auch an ihrer Unterseite 74 jeweils mit zwei Verstärkungsstreifen 76, 78, 80, 82 beschichtet. Die Verstärkungsstreifen sind im vorliegenden Beispielsfall jeweils entlang der Längsränder der Weicheinlage 70 vorhanden; der mittlere Bereich der Weicheinlage 70 ist daher unbeschichtet. Sofern die Verstärkungsstreifen über ein Tauchbad auf der Weicheinlage 70 aufgetragen werden, könnten auch die Seitenränder 84, 86 der Weicheinlage entsprechend beschichtet sein. Im vorliegenden Beispielsfall bleiben die beiden Seitenränder 84, 86 unbeschichtet.In the FIGS. 14 and 15 a soft insert 70 is shown in which it is possible to dispense with the use of an additional seam band. The soft insert 70 is coated in the present example on both its upper side 72 and on its underside 74 each with two reinforcing strips 76, 78, 80, 82. The reinforcing strips are present in the present example in each case along the longitudinal edges of the soft insert 70; the middle region of the soft insert 70 is therefore uncoated. If the reinforcing strips are applied to the soft insert 70 via an immersion bath, the side edges 84, 86 of the soft insert could also be correspondingly coated. In the present example, the two side edges 84, 86 remain uncoated.

Im Gegensatz zu dem in Fig. 14 und 15 dargestellten Ausführungsbeispiel könnte die Weicheinlage 70 auch lediglich auf ihrer Oberseite 72 oder lediglich auf ihrer Unterseite 74 mit einem Verstärkungsmaterial beschichtet sein. Es wäre auch möglich, das Verstärkungsmaterial auf der gesamten Oberseite 72 und/ oder auf der gesamten Unterseite 74 vorzusehen.Unlike the in FIGS. 14 and 15 illustrated embodiment, the soft insert 70 may also be coated only on its upper side 72 or only on its underside 74 with a reinforcing material. It would also be possible to use the reinforcing material provided on the entire top 72 and / or on the entire bottom 74.

Die Beschichtung der Weicheinlage 70 dient dazu, dass sich die Weicheinlage 70 nicht unkontrolliert ausdehnen kann, was zu unsauberen Nähten und nicht reproduzierbaren Ergebnissen führen würde. Darüber hinaus kann die Beschichtung dafür sorgen, dass die Weicheinlage leicht durch das Werkzeug der Nähmaschine transportiert werden kann, so dass hohe Nähgeschwindigkeiten erreicht werden können.The coating of the soft insert 70 serves to ensure that the soft insert 70 can not expand uncontrollably, which would lead to unclean seams and not reproducible results.
